S.C. Code § 44-48-20
The General Assembly finds that a mentally abnormal and extremely dangerous group of sexually violent predators exists who require involuntary civil commitment in a secure facility for long-term control, care, and treatment. The General Assembly further finds that the likelihood these sexually violent predators will engage in repeated acts of sexual violence if not treated for their mental conditions is significant. Because the existing civil commitment process is inadequate to address the special needs of sexually violent predators and the risks that they present to society, the General Assembly has determined that a separate, involuntary civil commitment process for the long-term control, care, and treatment of sexually violent predators is necessary. The General Assembly also determines that, because of the nature of the mental conditions from which sexually violent predators suffer and the dangers they present, it is necessary to house involuntarily-committed sexually violent predators in secure facilities separate from persons involuntarily committed under traditional civil commitment statutes. The civil commitment of sexually violent predators is not intended to stigmatize the mentally ill community.
